Gas safe peeps

[tommyplumb]

What does the ratio,ppm,co2 supposed to read when the boiler is safe?
Just had a boiler serviced & the corgi man left me with a piece of paper that says the ppm is 779 & co2 10.2.
What is the ratio?
Is this ok?

Boiler is a potterton profile 80e.

A Potterton Profile with a high CO reading like yours needs further investigation.They normally run better than that.
Headman, your comments indicate you know SFA.
0.012

A cracking first post there, Terry.
Obviously, you have no idea either, or you wouldn't have made a complete ass of yourself posting that drivel.

Tommyplumb, someone with more knowledge than myself, and more sense than Headcase will no doubt be along to answer your query.

I make the Ratio 0.0764

Co ppm / (Co2% x 1000)

 

[Space cat]

Excuse me for butting in as a humble mathematician - because I can only guess at what those numbers mean. (Would it be ppm CO and %CO2 in the flue gas? ) But I do know that the conversion factor from percent to ppm is 10,000.

Does that not make the ratio 0.00764? Or should I stick to particle accelerators?

Stick to particle accelerators.

779 ppm = .0779% CO in air

0.779/10.2 = 0.0076 co/co2 ratio

779/ (10.2x10,000)102,000 = 0.0076 co/co2 ratio.

Suggest Headcase should spend a little more time helping on here next time or maybe just STFU.

dont know what going on here, I still get a ratio of 0.0076

779/10,2= 76,372

76.372/10000= 0,0076

wrong ?

These 0000000000000s can be a PITA.........

779ppm
------------------------------------ = 0.0076 co/co2 ratio.
(10.2 CO2 x 10000) = 102,000

I would say that you don't really need to know what these numbers mean but obviously your service engineer doesn't either if I got a reading of co 779 ppm I would not just write that on a form and leave. They should be taking some further steps to SERVICE your boiler did they actually SERVICE the boiler or just stick an analyser in it?

 

[Charnwood]

Seems you owe me an apology charnwood , more sense? suggest you keep them fingers off the keyboard considering you aint got a clue son.

Apology? You've more chance of finding rocking horse faeces.

Why come on slinging abuse? If, as you claim, you knew the answer, why not just post it?
At least I did not claim to know the answer. Nor did I try Googling it.

779 ppm = 0.0779% CO in air

0.779/10.2 = 0.0076 co/co2 ratio

779/ (10.2x10,000)102,000 = 0.0076 co/co2 ratio.

I hate these mathmatical ones, its so easy to get it wrong.

But why does 0.0779% suddenly jump in the next line to be 0.779 ?

779ppm/10,000 = 0.077% co in air.

The 0.779 should of read 0.0779 , the missing zero is possibly the keypad getting sticky.

 

[sooey]

The analyser works all that out and displays the ratio, so what's the point?

Always best to check and check again when posting!

If you dont do it then someone else will always notice!

{sticky keypad or sticky fingers }

I do apologise for posting incorrect ratio results. (maths was my weak point )
I always relied on the fga which would do all the maths.
I'm big enough to apologise when wrong.
Headman, there is no need to come on here and behave like a complete prat and post such derogatory remarks. I hardly know you!
